With over 500 man-years of research and development, DRI has mastered the “art and science” of manufacturing rotors for both latent and sensible recovery as well as for dehumidification.

We are equipped with world-class test facilities that can be used to evaluate performances of Enthalpy Wheels and Desiccant Wheel. The company has also set up a state-of-the-art Laboratory to test and produce rotors capable of delivering extremely low Dew Point for specialized applications like lithium battery rooms. We also provide desiccant rotors for commercial fresh air treatment systems.

DRI has been awarded a success rating of 100% under the AHRI evaluation program consecutively, for the last seven years. We have also been participating members ever since the inception of the Eurovent certification program for Rotary Heat Exchangers.

DRI has a fully integrated rotor manufacturing facility with an in-house capability of coating, synthesizing, winding, metal working and surface finishing and a world class test facility for performance evaluation of Enthalpy Wheels.

The equipment manufactured by DRI is exported outside India to South East Asia, China, Indian Sub continent, West Asia, Africa and Australia as well as Japan, Korea, Europe and North America. DRI exports over 70% of its produced equipment to almost all countries in the world including Germany, Japan and North America.

DRI's "Green" products help optimize energy performance of the air conditioning systems. This results in a considerable reduction of installed tonnage, reduction in utility bills for the product's entire life cycle, enhanced IAQ and productivity and reduced health risks. DRI Products also help procure rating points for energy certification programs like Greenstar and LEED.

We, at DRI are committed to building a sustainable future. DRI is an active member of the Green Building movement and is doing its bit to help the movement across the globe.
